' Applicati on fled September e, 1923. Serial Ito/660,719.

This invention relates to improvements in wrapping machines and more particularly to machines of the type adapted to enclosean article in an inner carton and outer Wrapper. An important feature of the present invention resides in wrapping mechanism which formsa carton of'box-like form aboutan article of difl'erent form such as one with rounded sides, and without fastening the sides of the carton, encloses the same iii an outer wrapper of paper which serves to hold, the carton in. shape.- The' carton may conveniently be formed of a blank to' provide no overlapping sides, or at the most overlapping portions upon only the. topside thusecono- 1 mizing in material.

Other objects and advantages will be apparent from the following description and drawings in which; p i Fig. 1 is a side elevational view of the machine;

A machine constructed according to our invention is easily adapted for eneral appliose an article in a carton and an outer wrappen; In the form at present preferred the invention will be disclosedin'con'nection with the wrapping of an oval or circular shaped article such as a cake of soap or the like. Such'articles, being of a brittle or soft material are more easily wrapped when enclosed in a carton or contamer which provides a stiff symmetrical form to receive t-he outer wrapping material. To facilitate a clearunderstanding of the follow, We will first briefly describe the way and manner in which the article,-carton and wrapper are advanced through the machine for; the various assembling, folding and tucking operations. (See Fig. 18). Y

i The articlesA are successively fed to the machine in a horizontal plane and in the di- ,rection of the arrow a'preferably by a chain 7 deposited by the conveyer. The articles are chain onto the top of a reciprocating plunger Lin-the position A and as'the plunger 1 .moves to the left in Fig. 18, are allowed to fall in the direction of the arrowc onto a suit able support (not shown) where they are in the position A? and in line with or in the The article A is then advanced bythe plungerl in a direction at right angles to the direction of travel of the chain and as shown bythe arrow 01 while a carton C is nism from the direction indicated by arrow simultaneously advanced by suitable mechae. The article is thus brought to rest in the position A over the carton and between'cooperating vertically reciprocating plungers (not shown) which hold the article and carton in correct relative position and which are adapted to carry the same downwardly in the direction of the arrow f to a rest position C During this downward movement certain folding operations are performed upon the carton sides and the same is brought to rest at position C in the path of'a horizontal reciprocating plunger 2.

The partially folded carton and article are next advanced by the said plunger 2 in the direction indicated by arrow 9 from position C to the rest position C During this travel subsequent folds are made in the carton and the nearly completely folded carton isbrought to rest at C in the path of a horizontally. reciprocating plunger 3 that travels at right anglesto the plunger 2.-

A wrapper \V for the outer wrapping is advanced or fed downwardly and positioned as shown and in the path of or in line with the article and carton.

The article and carton are nextadvanced from position C by the plunger 3 in the direct-ion indicated byarrow it into a pocket of V a rotatable pocketed wheel indicated at position W During this movement the remaining fold. is. made uponthe carton and the wrapper'W is folded about three sides of the carton while an endtuck is made when the carton and wrapper are deposited in the before mentioned p'ocketof the wheel.

The wheel carries the partially wrapped carton in the direction of arrow j to a rest position W where a glue stripe is applied to suitable gluing mechanism.

A further rotation of the wheel carries the partially wrapped carton in the direction of the arrow is to'a rest position W It is then ejected from the wheel pocket 8 into suitable folding mechanism in which it is advanced in the direction of the arrow Z- Successive remaining, folds are made upon the wrapper during its passage through the folding mech- 'anism and the completely wrapped article is finally delivered into a brush lined discharge chute.

By reference to the drawings, the structure Wlll now be described in detail. A bed plate 10 is provided that is supported on-suitable uprights 11 which are preferably tied together by the horizontal struts 12 tozform a rigid and substantial frame-work.

A main driving shaft 13 extends transversely ofthe machine and is provided with tight andloose pulleys 14. A driven shaft 16 extends longitudinally of the bed 10 and is suitably journaled in hearings l6 -carried by the supports 11 see Figs. 1- and 3). Bevel gears 17 are fixed to the shafts 13 and 16 and are in intermeshing engagement for operatlngthe said shafts in a proper timed. relation. -.A hearing shaft 18 is fixed in the struts -12 andserves as a bearing for various rock 1ng levers as will later appear. A fixed bear-' ing rod 19 parallel to the rock'shaft 18 is fixed in suitable hangers 20 carried 'by the struts 12 and serves as a bearing for other the extending wrapper flap by a roll 4 of a drive the p y and belt n of spaced side plates (see Fig. 1) that are' supported by the brackets 26 and 27 secured to the bed plate 10. Endless chains 28 spaced apart a distance suflicient to receive an article ,therebetween are carried by' the loose idler sprockets 28 rotatably supported by the shaft 29 and are in driven engagement with the sprockets 3O fixed to a driven shaft 31. I The shaft 31 is rotatably carried by the. bearing standards 32 and 33 fixed upon the bed plate 10. Suitable chains 34 and 35 in enconnect the shaft 31 to the driving shaft 13 from which the conveyer chains are driven in a timed relation. Cross bars suitably connected between the chains 28 serve as pushers to advance the articles successively into the machine. An ,idler pulley 42 and a 'driving pulley 43 are journaled in the conveyer plates 25 and carry an endless article supporting belt 44 that is adapted to support the articles during their advan'cement by the chains 28. Chain and sprocket connections 45 between the shaft 29 and pulley 43 serve a proper timed relation with the chains :28.

As previously mentioned, the articles are .fed onto the top of plunger 1. As said plungr;

er reciprocates to the right in Fig. 3 the article drops onto a stationary plate best shown in'Figs. 1, 3 and 4, which plate is fixed to and supported by the standard 33. A vertical guide plate 51'carried by the brackets 32 and 33 serve as a stop against which the article abuts as it is carried into the machine by the chains. The cross plunger 1 is best shown in Figs. 1, 3 and 4 comprises a forward shoe portion 53 and a top horizontal plate 54. The .topplate is adapted when movedto the left in Fig. 3' to receive thereupon an article adyanced by the c'onveyer chains. When moving to the position shown in F 3 the article resting thereon is allowed to drop upon the plate 50. The plunger 53 and, plate 54 are carried by-a suitable bracket 56 slidably -mounted on the stationary rods 57 and 58 and receives its reciprocating motion by means of,

the'link- 59 and lever 60- pivotally mounted upon the rock shaft 21. A cam 61 fixed on- 'agement with the sprockets 36, 37, 3-8 and 39 the shaft 16' is providedlwith a suitable cam groove within'which a roll 62 of the lever 60 operates to move the lever for reciprocating the plunger 1. T

A vertically recpirocating elevator 63 having spaced article supporting surfaces 63 ,as shown in Fig. 2 and Fig. 4, is arranged to elevate toaheight corresponding substantially to the plate 50 there to receive a carton C and I The said elevator reeaeve an article A in their superposed position (see Fig. 3) is carried by a slidablevertical rod 64-. which is guided in the lower bearing 65 fixedto the fixed bearing rod 19 and in the upper bearing 66' extending from the bracket 66 secured'to the under-' side of the main bed plate 10. A shoe 67 fixed to the rod 64straddlesthe fixed guide bar 68 for sliding action thereon and which functions to prevent a turning action of the elevator. The rod 68 may be suitably secured to the members 65 and 66'. The elevator 63 is reciprocated (see Fig. 1) by means of a link 69 connected to a lever 70 which has a cam roll 71 in engagement with a suitable groove of a cam 7 2, fixed on the shaft 13, said lever 70- being pivoted on bearingrod 18. f

A vertically reciprocating plunger 75 that is in line with the elevator 63 is provided With four downwardly depending corner portions 76 that are adapted to engage a carton and to straddle the article A. (See Figs. 9, 10 and 17.) I Said plunger has straight vertical side portions which form square edges at the four corners thereof, against which and by the means of which the carton is folded into its rectangular shape. A plate 77 yieldingly reciprocating rod 82. The. reciprocating rod 82 is guided at its upper end ina bearing 83 fixed to an upwardly extendingsupporting rod 84 that is in turn fixed in a stationary movement by means of the standard 85 carried on the bed plate 10 (see Fig. 1). r The lower end of the rod.- 82 is preferably'guided (see Fig.3) in the bearing 66 and carries on its lower end a shoe member 86 that is in sliding engagement with a stationary vertical bar 87. The rod 82 (see igs. 1. and 3) isreciprocated by means of a link 88 pivoted to the shoe 86 and connected to a rocking lever89, pivoted on rod 18 and having a cam roll (not shown) working in a suitable groove of a cam 90 mounted on shaft13.

The carton magazine and mechanism for delivering cartons therefrom will now. be described with particular reference toFigs. 3 andel. A standard 100 fixed upon the bed plate 10 supports a horizontally reciprocating slide 101 that is adapted to support astack of properl scored carton blanks'C;

The sai slide is guided in its reciprocating the standard 100. The said slide as best shown-in Fig. 3 is provided at-its forward. portion with a ledge or somewhat sharp step shoulder 103 which functions as the slide is moved forwardly or to the rightin Fig. 3 toremove the lowermost carton from the stack.

and carry the same to its position A? and Q is then positionedas at C tion to. be carried under the folding. plate 120 overtheeleva'tor 63, as in the patent to Smith 1,313,863 of August 19, 1919. The stack of carton 'blanks'is held in position by means of, i

the forward vertical bars 104 and rear bars 105. The bars 104- have their lower ends spaced from the slide 101 a suflicient distance to allow the passage thereunder of one carton blank at a time. The slide. 101 is further provided at its forward end with open slots 101 to facilitate the said slide being moved forwardly while the elevator 63 is in an-elevated position (see Fig. 3

The slide 101 is reciprocated by the link '109 pivotally connecting it with the rocking lever 110. mounted on "the bearing shaft 111.

A connectingrod 112 connects the'said lever wlth a cam fork"1 13 slidably in the shaft 16 that is given a reciprocating movement by means of suitable groove 114 of cam 11 1 on the said shaft 16.

A bracket 106 rigidly fixed 84 supports the members 104 ferred toand has fixed to it 107 for guiding the article as it approaches its position A over the elevator..63. A latch 109 pivoted beneath the bracket 106 engages the rearward edge ofthe carton after it has been delivered upon the elevator and prepreviously respaced guides ,vents its displacement when the slide 101 is returned to the leftin F ig. 3. Upstanding' to the upright I its cam roll in engagement with a prongs 108 are carried by thebra'cket 33 and i are so positioned as to serve as stops for the carton blanks and'to properly locate the said blanks when they are fed forward to their position over the elevator 63.

The previously referred to plunger 75 and theelevator 63 are adapted to receive therebetween a carton C and anarticle A and are so timed that they descend in unison to lower the carton and article to a lower level or position C During this movement the side flaps of the carton are folded,-as shown in Fig. 18, and the mechanismjor performing this. operation will now be described with particular reference to Figs. 1, 2, 3 and 5. As the article and the carton blank are carried down by the plunger 7 5 and the elevator 63., the side. flaps 251 and 252 of the blank strike folding plates 116 and 117 (see Figs. Zand 10),,by meansof which they are folded upwardly as at C in Fig. 18. Theend flaps of the carton blank strike a fglder 118 at one 7 side of the path of the plunger 75 and a folding plate 120 at the other side. The article is sfipported by the standard 33 and bracket in Fig. 3 in positau 128 and has a shoe portion 126' that engages a guide 129 fixed to the bed plate 10 to prevent a turning action thereof. A link 130 pivotally connected to the head 126 is also functions to rock the said lever and thereby against the article.

' ence to Figs.

' link reciprocate the said plunger bars to the left in Fig. 3. This reciprocation of the plunger 2 moves the article and partially folded carton from the elevator onto the platform 122 also through the folders 119 and 120 previously referred to and finally deposits the partially folded carton in the position C or in a location in the path of the plunger 3 (see Figs. 1, 2. 3, 6 and 8.)

Folderplates and 141. are carried by the side Wall 142 of the platform 122, the former of which. functions as the article and carton are fed thereunder to fold the upwardlyextending side flap down upon the article leaving the opposite side fold extending upwardly in the space between the said folders. A folding finger 144 (see Figs. 2 and 13) having a portion 145 extending upwardly and through a suitable slot in the plate 122 1s designed to strike the end flap of the carton as it is fed thereagainst and to fold the same A stop 146 is provided on the upper side of the finger is adapted to strike against the under side of the platform 122 to limit its upward'movement and a compressionspring 147 beneath the finger tends to yieldingly press the finger upwardly for the folding operation. Separated side plates 148 carried by the platform122 are provided to hold the vertical side fold of the carton in place preparatory to the advancement of the carton and article to the right in Fig. 2 and in the direction of the arrow h.

' Theplunger 3 for advancing the carton and article will now be described with refer- 1. 2 and 3. A plurality of spaced bars 150 fixed to a reciprocating head member 150' are arranged to pass between and at the sides of the plates 148 (see Fig. 2). The said head 150 is guided in suitable gibs 151 fixed to the bed plate 10 and has a lug 152 depending therefrom to which is pivotally connected a link 153. The said 153 is pivotally connected to the long arm of a rocking lever 154 pivoted on the fixed shaft 1 9. The short arm 154 of the lever 154 is connected to a pull rod 155 having a fork 156 on its end that slides on the driving shaft 13. A cam roll 157 carried by the fork is in engagement with a cam groove in a suitable cam 158 on the said shaft whereby the said rod and lever are rocked to reciprocate the plunger 3 in a proper timed relation. An arm 154" extending downwardly from the e ector plungers later to be described. Means for supporting a wrapper W in position in the path of the carton and plunger will now be described with reference to Figs. 1, J. and 6. Standards 300 and 301 fixed to the bed plate 10 support an angular shaped table 302 the horizontal leg of which is flush with the platform 122 and is adapted to receive the carton and wrapper as they are advanced thereunto by the plunger 3. Side guides 303 are caried by the standards 300 and 301 and function to guide the advancing package and to start the side fold 254 in the wrapper W as the carton and wrapper are advanced therebetween. A transverse bar 304 carried by the bed plate 10 carries adjustable members 305 in which are rigidly secured upstanding rods 306 as shown that are adapted to support a wrapper W in position and in the path of the carton to be advanced thereto. \Vrappers are supplied to the wrapper guides 30? from any suitable wrapper feeding means which means may be supported above the bed plate by the uprights 84 and 85. It will be apparent that any means for supplying wrappers may be employed to deliver a wrapper of the desired dimensions in a timed relation with the other units of the machine.

A wiper member 158 pivoted at its ends in the supports 150 and 151 is provided with a coil spring 159 on one of its pivotal extensions which tends to yieldingly hold the said gate in the position shown in Fig. 6. As the carton and wrapper are advanced to the right in the direction of arrow h (in Fig. 6) and into a pocket of the tumble box the said gate exerts a tension upon the wrapper to fold thesame against the carton in the usual manner.

The tumble box will now be described with reference to 1, 2 and 6. It comprises a plurality of pockets 160 having the usual resiliently mounted upper and lower article engaging plates 161. Bottom members 162 located in each of the pockets are rigidly connected by slidablerods as in the patent to Smith 1,306,358 of June. 10. 1919. Folder lever 154 is connected to and serves to operate plates 163 are carried by each of the members I 162 at the ends thereof that are adapted to fold an end tuck in the wrapper as it is inserted with the carton into the said pocket. The tumble box is preferably rotated through 90 degrees between its rest positions W V and W and receives its intermittent rotary motion by means of the following mechanism best shown in Fig. 2. A combined driving gear and geneva and 171 respectively are rotatably mounted on a stud 172 fixed to the bed plate 10 and the said geneva is driven in the usual manner by a Geneva roll and crank 173 fixed to the driving shaft 13. A driven gear 174 fixed to the-tumble shaft 175 is in meshing enga ement with the said driving gear 170 and rom which it is intermittently rotated.

Mechanism for applying glue to the extending wrapper flap when the tumble box has carried the same to the position W will now be described, with particular reference to a member 186 fixed to the upright 85. The

usual ratchet and pawl (not shown carried by the lever 184 and roll 183 are a apted to rotate the said roll 183 as the container 180 is swung for the purpose of presenting a new portion of the rolls surface each time it engages a wrapper flap. Such mechanism is of common and well known construction. The container 180 receives its swinging motion by means of a connecting rod 187 that is connected to the upper end of the bell crank 181 and that has its fork 188 in sliding engagement with the shaft 13'- from which it receives a reciprocatory motion by means of t-heusual cam and roll, etc. (notshown).

Ejecting levers 190 for engaging the tumble box members 162 willnow be described with reference to Figs. 1 and 2. lhe said levers are pivotally mounted upon a rocking shaft 191 that is rotatable in 2. depending bracket 193 carried on the underside of the main bed plate 10. lhe said levers are spaced apart sufficiently to allow the tumble box to rot-ate therebetween and carry in their upper ends inwardly extending pins 194 that are adapted to abut the rear side of the members 162 in their swinging movement to the right in Figs. 1 and 2 whereby the said memher is moved outwardly to eject a partially wrapped carton in the usual and well known manner. One of the levers 190 has a depending end portion 190' that is suitably con nected by a rod 195 to the lower end 154" of the lever 154 previously referred to and best shown in Fig. 3 and from which the said lever receives its rocking motion.

' As the partially wrapped article is ejected from the pocket in position W it is advanced into a folding mechanism now to be descrlbed and by the means of which the final folding operations are accomplished. A transverse rod 200 (see Figs. 1 and 2) is rlgidly supported above the bed plate 10 by means of the standard 201 fixed to the bed plate 10 and the bracket 202 fixed th the upright rod 85 and has fixed thereto a member 203 having an arm 204 extending to the left therefrom. A swinging arm 205 pivoted on said arm carries a friction pad 206 that is adapted to engage the extendingwrapper flap as it is moved there ast and to exert a dra thereagainst. A co1 spring 207 carried by t e pivot of the arm s adapted to yieldingly hold the said arm 1n the position shown in Fig. 1.

F oldlng chute bottom plates 208 are fixed to the bed plate 10 and have fixed thereto at thenforward ends the end tuckers 209 that are spaced apart in the usual manner to allow a carton to pass therebetween and are adapted to form an end tuck in the wrapper as it is advanced therepast. Side folding plates 210 are supported by brackets 211 depending from and fixed to the rod 200 and are spaced apart a distance to allow a partially wrapped carton to advance therebetween. These plates fold certain of the wrapper flaps as will later be described. Folder plates 212 for forming the final folds are pivotally mounted on vertical pivots 213 of the members 208 and are connected by a coil spring (not shown) to cause the said plates to yieldngly press upon an article and wrapper as the same is fed therebetween during the fold- 111g operation. A brush 214 having its bristles dependmg downwardly therefrom for exertmg friction upon the upper side of the article as 1t is advanced through the folding chute s supported by a suitable bracket 215 depending from and fixed to the rod 200.

A shaft 216 rotatably mounted in bearings 21'? and 218 has fixed thereto members 219 that carry suitable glue containers 220 for supplying glue to the wrapper flaps 258 extending from the folding chute. Suitable glue rolls 221 rotatablyinounted in the containers 220 and extending through slots in the bottoms thereof present a small portion of their periphery having glue thereon to the extending wrapper flaps. The said. shaft 216 is rocked to contact the dauber roll and wrapper flap in a manner shortly to be described.

The completely wrapped articles are ejected from the folding chute to a position beneath the swinging and reciprocating arm 223 shown in Figs. 1, 2, 8 and 8 The said arm 223 is fixed to a shaft 224 rotatably carried in a slide 225 that is adapted to reciprov cate upon a rod 226 fixed in the before mentioned bracket 218 (see Figs. 1 and 8.) A stationary guide bar 227 is also fixed to the bracket 218 and upstanding lugs 228 carried by the slide 225 straddle the said bar 227 to prevent a turning of the slide 225 during its reciprocation back and forth along the rod 226.

A rock shaft 230 rotatable in bearings 231 of the standard 218 is rocked in a proper timed relation for the purpose of operating the said arm 223 and glue daubers 220 previously described by the following means and best shown in Figs. 1, 2, 7 8 and 8 A cam fork 233. slidable upon the shaft 13 and having a cam roll 234 in engagement with a suitable cam groove of a cam fixed upon the said shaft receives a reciprocating motion therefrom and is connected by a rod 235 to an upwardly exten'din lever 236 fixed to the end of shaft 230 whereidy the said shaft is rocked. A link 237 (see Figs.2 and 7) pivotally connecting the lever 236 and a lever 238 fixed to'the shaft 216 is adapted to rock the shaft 216 whereby the glue daubers carried by the shaft 216 are operated. A slotted lever 238 fixed to the shaft 230 and depending downwardl therefrom receives a roll 239 carried by t 1e lever 240 fixed to the arm shaft 224 and as the said shaft 230 is rocked the shaft 224 is likewise rocked by means of the slotted lever 238 roll 239 and lever 240, whereby the arm 223 is swun downwardly from the position shown in ig. 8 The lever 240 is provided with an abutment 240' (see- Figs. 2 and 8) that is adapted to abut a pin 242 projecting from the slide 225. As the lever 240 and arm 223 are swung downwardly through an angle sufficient to carry a wrapped package from its horizontal to its vertical position shown in Fig. 8 the abutment 240 engages the pin 242 whereby further relative swinging movement of said lever 240 is prevented and the continued swinging movement of slotted lever 238 acts to move said lever 240 and slide 225 forwardly along its guide rod 226, a distance equal to the thickness of one package, orrather from the position 244to that indicated as 245 in Fig. 8*. Side brushes'246 having their bristles inclined rearwardly are provided and a aresuitably supported on the frame 10 in such a manner as to receive therebetween the wrapped packages as they are fed thereinto.

' Bottom bars 247 having their forward ends curved as shown are supported on suitable cross bars 247 fixed to the brushes 246 and are adapted to support the packages as they are advanced through the said brushes.

In operation articles A are placed between the chains 28 and cross bars 40 thereof and rest upon the endless belt 44. The said chains and belt are driven continuously in the direction of the arrow A to carry the articles to the position A where they rest upon the top plate 54 of the plunger 1 which in its timed relation is moving to the right in Fig. 3. When the said plunger has reached the extreme position as shown in Fig. 3, saidarticle dropsdownwardly from the top plate 54 and onto the stationary supporting plate 50. This dropping action allows the chain and its bars to pass thereover without interfemales with the article. in its position A and now in the path of the plunger 1.

Cartons C of a'desiredshape and size and that; are properly scored to form a package of the-shape and form desired are held in the carton stack by the guides-104 and 105 thereof. The carton lunge'r 101 in its reciprocation-to the rig t' in Fig. 3 removes from the bottom of the stock one carton and carries it forwardly into the position A where its corners are engaged by the upstanding guides 108 which function to accurately position the carton. During the latter part of this forward movement of the plunger 101 the article plunger 1 also moves to the left and toward the plunger 101 and is so timed that the article A and carton reach their destination, position A at substantially the same time at which time the elevator 63 is in be seen from Fig. .3 the said plunger 101 is slotted at 101" to facilitate the said elevator being raised to its carton supporting position while the cart-on plunger 101 is approaching its forward or. advanced position.

After the carton and article have been'lomultaneously and as the article and carton pass the folder plate 118 (see Fig. 3) the rear end flap 250 of the carton is folded upwardly. As the carton and article are forced between the folders 116 and 117 the sides 251 and 252 are folded upwardly as shown in Fig. 18 and are held in this folded position by the lower upright portions of thefolders 116-and 117. The plunger 2 nowcommences its reciprocation to the left in Fig. 3 and in the direction of the arrow 9 and the bars 127 of the said plunger 2 as they contact with the rear end of the carton serve to hold the rear end flap 250 of the carton in position. The plunger '2 carries the said carton and article to position C and during its travel thereto the top fold 253 is completely folded down upon the article by means of the horizontal folder plate 119 (see Fig. 2)which fold is held against the package by the plate 140 as the carton and article reach the rest position C The units raised carton supporting position. As will folded flap 254 of the .c'arton enters a slot formed between the plates 140 and 141 and stands uprightly therein .as shownin Figs.

12 and 18. The article and partially foldedcarton in the position C are directly in the g path of the plunger 3 and are to be advanced A wrap-per W is delivered by suitable wrapper-feeding mechanism to the position shown in Figs. 1 and 18 and in the path of the said partially folded carton. The plunger 3 now advances in the direction of the arrow h and engages the longitudinal sideof the almost completely folded carton and advances the forwardly. During this advancement thereby in the direction indicated by arrow h.

On entering thefolding chute the extended wrapper flap 255 is laid down against the cartonby ,means of the upper brush 2140f the chute and the end tucks 256 are formed by the end folders 209 located on either side of the said folding chute. The

package remains in the folding box and in" 'the form shown' inFig. 16 until a subsequent package is ejected thereinto. Y

The next succeeding pack-age ejected into the tumble box abuts. the package previously referred to and moves the same therealong a distance. substantially equal-to the width of one package.

During this latterjmovement the .upper flaps 257 are folded down and against the end of the package by the side folders 210 forming. the wrapper as shown in Fig- 16 .and leaving the lower flaps .pro'ject-. ing from beneath the said folders as shown by dotted "lines 258. -The said package remains .inthis position until another partially wrapped package'is ejected from the tumble box, and while so positioned the glue daubers 220 are moved downwardly toapply a stripe- 'of adhesive to the said flaps 258 in the usual,

manner. Another article ejected into the tumble box moves the articles contained therein along once more a distance equaling the width ofonepackage and as the package is .by succeeding l I folding die, means for'positioning The ejector arms 190-now advance tothe right in Fig. 2 and the pins thereof engage.
